If you pick up a basic TT02 kit, in my opinion, don’t waste your money buying the CVA plastic oil filled dampers.

For the same money you can buy the Yea racing aluminium which are basically a copy of the TRF. The threaded shock collars allow you to adjust ride heigh much more accurately.

Unless your planning to race in Tamiya TCS, which only allows for Tamiya parts

However if you plan on hitting some dirty / rallye, stick with TT02.

Thank you. How about parts for the TA? Would it be an issue?

Definitely add camber to front and back. Zero toe in back is causing the instability. I’m running 2° In on my rear and 1° out on front

I do have non-detergent oil if that's the issue.

What's the most robust option for rear toe? I'm using the body posts on the rear bumper so need the rear bumper to be attached.
I could fabricate something. I'd 3d print something but no plans openly available and I haven't taken the plunge into designing yet.

The current state of the chassis.
Upon further looking at the yeah racing rear toe mount, It might work with the bumper; I just need a caliper measurement from the front to back of the adjustable mount where the screws go.

Hard to find parts are:
1. Replacement chassis
2. Belts.. V1 in particular

all other bits are more or less interchangeable and upgradable with later cars.. eg you can use suspension arms from 418, 419, 420 with no issues.

Belt, you can switch to V2 belt if you change the pulleys, which is better anyways. V2 belts can still be found.

Hop Up.. there is still plenty of inventory out there

Not sure the brand but here's where I got them. They have really good grip and the price isn't bad either.
4PCS 28MM 1/10 On Road RC Car Tires With Foams (Can be used for 26mm wheels) | eBay
Mounted on generic aluminum wheels.

This is my TA05 V1 60mph car.

I feel like something is off on the chassis. I put the shorter lower eyes on the shocks and moved the front shocks in up top. I have 2mm droop in the front and no rear droop with the mini CVAs.
Still pulls to the left pretty hard. I also have the 30mm foams. I'll have to get the ride height but its about 6mm front and 7mm rear.

Hi guys. Do you guys recomend 2 oil diffs or just rear and in the front stock with thick grease or locker? I am looking at the YeahRacing one.

Thank you

I typically run front diff locked / spool and rear with Oil filled. The only car I run a front diff on is my XV01 which is used for Rallye on dirt, snow etc.. that has a gear diff, but with very thick fluid

Thanks again.

Silly putty in the front diff will make it into a solid spool, and it can be easily removed without residue later should you want to get the diff action back. Also won't leak.....bonus.
